Specification of Letters Patent.

Patented May 23, 1916.

Application filed July 2, 1915. Serial No. 37,723.

T 0 all whom it may concern Be it known that I, HARRY C. WATSON, a citizen of the United States, residing at Lancaster, in the county of F airfield and State of Ohio, have invented certain new and useful Improvements in Pulp-Beaters, of which the following is a specification.

My present invention relates to pulp beaters and has for its main object the provision of an improved structure, constituting the abutting surface between which the pulp is passed and ground to dry out its fibers and reduce it to the finely divided state necessary for its successive working.

'A further object of my invention resides in so constructing and so arranging this structure of abutting surfaces or filling as they are commonly known, that they are easily renewable and repairable, the fillings of both the cone and shell being so con structed that one or both of them may be removed from its applied position with comparative ease. This arrangement enables me to renew the heavy working parts of the machine after once these parts have become worn out. 1

These objects I accomplish by the structure shown in the accompanying sheets of drawings, in which similar characters of reference designate corresponding parts, and in which:

Figure l is a view in central section of the shell of a conventional type of pulp beater. Fig. 2 is a face view of the structure shown in Fig. 1, Figs. 3 and 4: are top plan and side views respectively of one of the shell filling sections, Fig. 5 is an end view looking froni the left of the structure shown in Fig. 3, Fig. 6 is a central vertical section of a cone adapted to cooperate with the shell shown in Fig. 1. Fig. 7 is an end view looking from the left of the structure shown in Fig. 6, Figs. 8 and 9 are top plan and side elevational views respectively of one of the filling sections applied to the cone shown in Fig. 6. and, Fig. 10 is a central vertical section of the cone and shell shown in their cooperative relation.

Referring to the drawings, the shell is designated by the reference numeral 1, this shell being provided with an inlet portion 2 and a cap 3 covering its outer open end, this cap being further provided with an outlet portion 4. The inner end of the cone is provided with an annular shoulder 5 forming a grooved into which the beveled-end of the inner surface.

inner end of the filling sections 7 are adapted to fit. It will be noted that these filling sections are provided in suitable numbers and so shaped that they exactly fit the inner surface of the shell, the outer surfaces of these sections being smooth to fit the smooth I The outer ends of the cone sections are somewhat larger than the inner ends and are provided with cut-out portions such as shown at 8, these cut-out portions forming an annular groove when in assembled, relation to accommodate the ring shown at 9. This ring is preferably of a somewhat resilient nature and is split as shown at 10, the ring in this manner being capable of a slight expansive action to effectively hold the filling sections in place when the cap 3 is removed from its operative position, as, for instance, when it is desired to inspect the interior of the beater as a whole, or to renew or replace the cone. Reference to Fig. 10 will show that the cap 3 will itself hold the shell sections in place when the entire machine is in its complete of the desired metal and are provided on their inner surfaces with inwardly eXtend-.

ing ribs 11, these ribs being arranged to extend obliquely to the axis. of the machine and are further provided in such spaced relation as to present spaces 12 between them, into which the pulp may pass.

The cone itself is designated as a whole by the numeral 13, this cone being provided with a bore 14 at its inner end upon which the shaft 15 is mounted and is further provided with a spider arrangement 16 at its outer end, into which the shaft 15 also fits as is shown more particularly in Fig. 10. The inner end of this cone is formed with an' annular shoulder 17, this shoulder being so grooved to present angular passage-- ways 18 to cooperate with the spaces formed by the ribs on the fillings in order to permit the free passage of the pulp. The shoulder 17 forms an annular groove 19 into which the inner end of each of the cone filling sections2Q securely fit, the outer edge of this cone being also provided with an annular shoulder 21 to serve as an abutment for the outer ends. of each of the filling sections. Each filling section is further provided with a number of countersunk bolt holes 22 through which the bolts 23 may pass to accommodate the nuts 24 on their outer ends and located within the hollow cone 13. In this manner.

the filling sections are all rigidly held in position and it will be further noted that each of these, filling sections is provided with a similar arrangement of outstanding ribs these ribscoiiperating with the ribs on the shell filling to serve the purpose ofdisin- V tegrating the fibers of the pulp.

From the foregoing, it will be apparent that I have provided a type of beater whei'ein both the shell and cone fillings maybe removed and replacediwhenever desired. It is customary to wear these fillings down until their ribs are substantially flush with the body, at which time it is, of course,

necessary to remove them and replace them. The cone may be removed by removing the cap 31, and this removal will not cause the collapse of the fillings within the shell, inasmuch as the-ring 9 is in such position as to permanently hold them in place. Further,

this ring is made split in order that the workmanship-of the annular grooves 8 need not be absolutely perfect. In this connection, the expansive nature of the ring is also desirable, since" it may be contracted or expanded to suit conditions.

What I claim, is; 1. In a pulp beater, a conical shell to which pulp is adapted to be ted Withdrawn, a 'cone fitting within said shell and adapted to be rotated therein, an annular shoulder on the inner end of. said cone, an imtstanding shoulder on the outerend of said cone, aphu'ality of suitably shaped filling sections fitting in the space between holes, bolts for attaching said sections to said. cone, and a' plurality of outstanding to fit in said groove to hold said sections in place, anda suitable cone Within, said shell adapted to be rotated therein. 7
